Description

Technical Field

[0001] This invention relates to the field of bridge maintenance technology, and in particular to a device for repairing expansion joints on municipal highways. Background Technology

[0002] Bridge and highway expansion joints are structures deliberately preserved when constructing highways on bridges, primarily to prevent factors such as temperature changes from affecting the safety of bridges and highways.

[0003] In the process of repairing expansion joints of highway bridges, it is necessary to first clean the mud, sand, and other debris inside the expansion joints. In the existing technology, the cleaning of expansion joints is usually done manually by multiple workers. One worker first uses a stick to break up the clumps of mud, sand, and other debris inside the expansion joint, and then another worker uses a vacuum cleaner to suck out the broken debris, thus cleaning the expansion joint. The process of manually breaking up the debris requires a lot of physical strength and is not very efficient. When the vacuum cleaner is used to absorb the debris, the worker needs to hold the vacuum hose and constantly adjust the position of the vacuum hose to absorb the debris inside the expansion joint, which consumes a lot of energy and requires multiple people to take turns to maintain the bridge expansion joints. Summary of the Invention

[0004] The purpose of this invention is to provide a repair device for expansion joints on municipal highways to solve the problems mentioned in the background art.

[0005] The technical solution of the present invention is: a municipal highway expansion joint repair device, comprising a mobile cleaning frame, rollers and a cleaning motor. The bottom of the mobile cleaning frame is provided with rollers, and the cleaning motor is installed on the mobile cleaning frame. It also includes a rotating frame, a cleaning conveyor belt, cleaning plates and a collection mechanism. The output shaft of the cleaning motor is connected to one end of the rotating frame, and the other end of the rotating frame is rotatably mounted on the mobile cleaning frame. A cleaning conveyor belt is provided between the mobile cleaning frame and the rotating frame. Cleaning plates are evenly spaced on the cleaning conveyor belt. The ends of the cleaning plates are provided with shovels. The collection mechanism is installed on the mobile cleaning frame and is used to collect debris brought out by the cleaning plates from the expansion joint.

[0006] Furthermore, the cleaning plate includes fixed push blocks and raised rods. Fixed push blocks are symmetrically fixed to the cleaning plate, and raised rods are evenly arranged on the cleaning plate. The raised rods cooperate with the cleaning plate to carry out the debris in the expansion joint.

[0007] Furthermore, the collection mechanism includes a mounting frame, a limiting strip, a collection frame, a first pulley, a transmission belt, a second pulley, a rotating shaft, a first torsion spring, and a cleaning plate. The mounting frame and the limiting strip are fixedly connected to the movable cleaning frame, and the collection frame is rotatably connected to the movable cleaning frame. The limiting strip supports the collection frame from the bottom. The rotating shaft and the first pulley are rotatably connected to the mounting frame, and the second pulley is fixedly connected to the rotating shaft. The transmission belt is wound around the first pulley and the second pulley. The cleaning plate is fixedly connected to the rotating shaft, and the first torsion spring is provided between the cleaning plate and the mounting frame.

[0008] Furthermore, it also includes a crushing mechanism, which is used to break up hard debris within the expansion joint.

[0009] Furthermore, the crushing mechanism includes a movable crushing frame, a third pulley, a transmission belt, a rotating rod, a sliding frame, a crushing rod, and a connecting sleeve. The movable crushing frame is fixedly connected to the movable crushing frame, and the third pulley is rotatably mounted on the movable crushing frame. A transmission belt is wound between the third pulley and the rotating frame. The rotating rod is fixedly connected to the third pulley, and the sliding frame is slidably connected to the movable crushing frame. The sliding frame has a slotted hole, and one end of the rotating rod is slidably mounted in the slotted hole on the sliding frame. The connecting sleeve is fixedly connected to the sliding frame, and the crushing rod is located inside the connecting sleeve.

[0010] Furthermore, the crushing mechanism also includes a rotary guide tube, a drill bit, and a connecting block. The rotary guide tube is fixedly connected to the movable crushing frame, the drill bit is fixedly connected to the crushing rod, and the connecting block is fixedly connected to the crushing rod. The connecting block is slidably disposed inside the rotary guide tube, and the crushing rod is rotatably connected to the connecting sleeve.

[0011] Furthermore, the connecting sleeve includes a limiting plate, a rotating plate, and a third torsion spring. The limiting plate is fixedly connected to the outside of the connecting sleeve, and the rotating plate is rotatably connected to the outside of the connecting sleeve. A third torsion spring is provided between the rotating plate and the connecting sleeve.

[0012] Furthermore, it also includes a guide frame, a rotating plate, a rotating rod, a spring telescopic rod, a second torsion spring, and a sliding plate. The rotating rod is rotatably connected inside the movable cleaning frame, the guide frame is fixedly connected to the collection frame, one end of the rotating rod is fixedly connected to the rotating plate, the end of the rotating rod near the collection frame is fixedly connected to the spring telescopic rod, the sliding plate is slidably connected inside the guide frame, one end of the spring telescopic rod is rotatably connected to the sliding plate, and a second torsion spring is provided between the spring telescopic rod and the movable cleaning frame.

[0013] Furthermore, both the sweeping plate and the sliding plate are equipped with soft bristles.

[0014] Furthermore, the drill bit has external threads on its outer side.

[0015] The beneficial effects of this invention are as follows: 1. This application can replace manual cleaning of bridge expansion joints. Workers only need to push the equipment along the expansion joint to clean the debris inside the expansion joint, which reduces labor consumption and improves cleaning efficiency.

[0016] 2. The cleaning plate is equipped with a shovel at the end. The shovel can scoop the debris in the expansion joint into the cleaning plate. During cleaning, the cleaning motor drives the rotating frame to move, which in turn drives the cleaning plate to transport the debris out of the expansion joint. The protruding rods on the cleaning plate hook out various debris in the expansion joint, realizing the function of quickly cleaning the debris in the expansion joint.

[0017] 3. When the cleaning plate rises with debris, the fixed push block cooperates with the first pulley to sweep the debris on the cleaning plate into the collection frame, preventing the debris on the cleaning plate from falling into the expansion joint, so that the equipment can continuously clean the debris in the expansion joint.

[0018] 4. Debris entering the expansion joint may clump and harden, and stick to the inner wall of the expansion joint. Before the cleaning plate enters the expansion joint, the breaking rod moves up and down with the sliding frame to break up the hard debris in the expansion joint, so that the debris can be removed from the inner wall of the expansion joint, making it easier to clean up the debris later.

[0019] 5. When the crushing rod descends, the connecting block drives the crushing rod to rotate, and the drill bit rotates accordingly to improve crushing efficiency. When the connecting sleeve rises, the rotating plate becomes horizontal and flips over the crushed debris, while scraping away the debris remaining on the inner wall of the expansion joint.

[0020] 6. When maintenance is complete or when there is a lot of debris in the collection box, manually turn the rotating plate. The rotating plate drives the guide frame and collection box to rotate through the rotating rod and the spring telescopic rod. During the rotation of the collection box, the debris slides outward. After the collection box rotates through a certain angle, it is limited by the limiting strip. At this time, the spring telescopic rod drives the sliding plate to move along the guide frame. The sliding plate pushes the remaining debris in the collection box outward, realizing the function of cleaning the debris in the collection box.

[0021] 7. The soft bristles on the sweeping plate and sliding plate make full contact with the surfaces of the cleaning plate and collection box, cleaning away debris from the surfaces of the cleaning plate and collection box, and the bristles are replaceable. Attached Figure Description

Detailed Implementation

[0024] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0025] Example 1: As Figures 1-10As shown, a municipal highway expansion joint repair device includes a mobile cleaning frame 1, rollers 102, a cleaning motor 2, a rotating frame 201, a cleaning conveyor belt 202, cleaning plates 203, and a collection mechanism. The bottom of the mobile cleaning frame 1 is equipped with rollers 102, which contact the bridge. The cleaning motor 2 is mounted on the mobile cleaning frame 1, and its output shaft is connected to the rotating frame 201. The rotating frame 201 has a structure for winding the cleaning conveyor belt 202. The cleaning motor 2 drives the rotating frame 201 to rotate. The other end of the rotating frame 201 is rotatably mounted on the mobile cleaning frame 1. A cleaning conveyor belt 202 is positioned between the mobile cleaning frame 1 and the rotating frame 201. Cleaning plates 203 are evenly spaced on the cleaning conveyor belt 202, and each cleaning plate 203 has a shovel at its end. The cleaning plates 203 shovel up debris from the expansion joint, and any debris not shoveled out is pushed forward. The collection mechanism is mounted on the mobile cleaning frame 1 and is used to collect debris carried out of the expansion joint by the cleaning plates 203.

[0026] When cleaning the expansion joint, first place the mobile cleaning frame 1 on the expansion joint so that the roller 102 contacts the bridge. Then start the cleaning motor 2. The cleaning motor 2 drives the cleaning conveyor belt 202 to rotate through the rotating frame 201. When the cleaning conveyor belt 202 rotates, it can drive the cleaning plate 203 to move. The cleaning plate 203 moves in the expansion joint and can lift the debris remaining in the expansion joint outward. When the cleaning plate 203 passes the collection mechanism, the collection mechanism sweeps the debris off the cleaning plate 203 and collects it. During the cleaning process, the mobile cleaning frame 1 is manually pushed to move along the expansion joint of the bridge to achieve the function of cleaning the expansion joint and collecting the debris.

[0027] Example 2: Based on Example 1, such as Figure 3 As shown, the cleaning plate 203 includes a fixed push block 2031 and a protruding rod 2032. The fixed push block 2031 is symmetrically fixed on the cleaning plate 203. The fixed push block 2031 is used to drive the collection mechanism to run. The protruding rod 2032 is evenly arranged on the cleaning plate 203. The protruding rod 2032 cooperates with the cleaning plate 203 to carry out the debris in the expansion joint, while preventing the debris from falling off the cleaning plate 203.

[0028] When the cleaning plate 203 moves into the expansion joint, the protruding rod 2032 on the cleaning plate 203 contacts the debris in the expansion joint and lifts the debris upward. The debris, the protruding rod 2032, and the cleaning plate 203 rise synchronously with the cleaning conveyor belt 202. When the fixed push block 2031 contacts the collection mechanism, the collection mechanism operates and collects the debris on the cleaning plate 203, thus realizing the function of collecting the debris on the cleaning plate 203.

[0029] like Figure 2 , Figure 4 and Figure 5As shown, the collection mechanism includes a mounting frame 103, a limiting strip 104, a collection frame 3, a first pulley 301, a transmission belt 302, a second pulley 303, a rotating shaft 304, a first torsion spring 305, and a cleaning plate 306. The mounting frame 103 and the limiting strip 104 are fixedly connected to the movable cleaning frame 1. The limiting strip 104 is rhomboid in shape, and both its upper and lower surfaces are flat. The collection frame 3 is rotatably connected to the movable cleaning frame 1. The collection frame 3 is used to store debris scooped up by the cleaning plate 203. The limiting strip 104 supports the collection frame 3 from the bottom. The rotating shaft 304 and the first pulley 301 are rotatably connected to the mounting frame 103. Figure 4 It can be seen that the first pulley 301 has a protruding structure at its eccentric position. The protruding structure at the eccentric position of the first pulley 301 contacts the fixed push block 2031. The second pulley 303 is fixedly connected to the rotating shaft 304. The first pulley 301 and the second pulley 303 are wound with a transmission belt 302. The cleaning plate 306 is fixedly connected to the rotating shaft 304. The cleaning plate 306 has multiple sets of bristles arranged in an array. The bristles are made of elastic rubber. The cleaning plate 306 can rotate with the rotating shaft 304. A first torsion spring 305 is provided between the cleaning plate 306 and the mounting bracket 103. The two ends of the first torsion spring 305 are fixed to the cleaning plate 306 and the mounting bracket 103 respectively. The first torsion spring 305 is used to drive the cleaning plate 306 to rotate and reset.

[0030] During the upward movement of the cleaning plate 203, the fixed push block 2031 on the cleaning plate 203 will contact the protruding structure at the eccentric position of the first pulley 301 and push it to rotate. The first pulley 301 drives the second pulley 303 to rotate via the transmission belt 302. The second pulley 303 drives the sweeping plate 306 to swing upward via the rotating shaft 304, causing the first torsion spring 305 to store force. There is a height difference between the first pulley 301 and the second pulley 303, so the sweeping plate 306 will not contact the cleaning plate 203 during the upward swing. When the fixed push block When 2031 moves to the middle height of the transmission belt 302, the fixed push block 2031 disengages from the protruding structure at the eccentric position of the first pulley 301. Under the torque of the first torsion spring 305, the cleaning plate 306 will quickly swing downward to reset. At this time, the bristles on the cleaning plate 306 will contact and drag the debris on the cleaning plate 203, thereby sweeping the debris on the cleaning plate 203 into the collection frame 3, realizing the function of sweeping the debris on the cleaning plate 203 into the collection frame 3. Since the bristles are made of elastic rubber, they will not hinder the upward movement of the cleaning plate 203.

[0031] Example 3: Based on Example 2, such as Figures 7-10As shown, it also includes a crushing mechanism, which is used to break up hard debris in the expansion joint; there may be hard debris in the expansion joint, which will affect the operation of the cleaning plate 203. Before the cleaning plate 203 extends into the expansion joint, the crushing mechanism crushes the hard debris in the expansion joint.

[0032] like Figures 7-10 As shown, the crushing mechanism includes a movable crushing frame 101, a third pulley 5, a transmission belt 501, a rotating rod 502, a sliding frame 503, a crushing rod 505, and a connecting sleeve 507. The movable crushing frame 101 is fixedly connected to the movable cleaning frame 1. The bottom of the movable crushing frame 101 is also provided with a roller 102. The third pulley 5 is rotatably mounted on the movable crushing frame 101. A transmission belt 501 is wound between the third pulley 5 and the rotating frame 201. The rotating frame 201 drives the third pulley through the transmission belt 501. 5. Rotation, a rotating rod 502 is fixedly connected to the third pulley 5, and a sliding frame 503 is slidably connected to the movable crushing frame 101. The sliding frame 503 is provided with a slotted hole. One end of the rotating rod 502 is slidably set in the slotted hole on the sliding frame 503. When the rotating rod 502 rotates, it drives the sliding frame 503 to slide up and down along the movable crushing frame 101. A connecting sleeve 507 is fixedly connected to the sliding frame 503. A crushing rod 505 is rotatably installed in the connecting sleeve 507. The crushing rod 505 moves up and down to break up the debris in the expansion joint.

[0033] When the cleaning motor 2 is running, the cleaning motor 2 drives the transmission belt 501 and the third pulley 5 to rotate through the rotating frame 201. When the third pulley 5 rotates, it drives the rotating rod 502 to rotate. When the rotating rod 502 rotates, it drives the sliding frame 503 to slide up and down along the movable crushing frame 101. The sliding frame 503 can also drive the crushing rod 505 to move up and down through the connecting sleeve 507. During the up and down movement of the crushing rod 505, the debris in the expansion joint is crushed, realizing the function of crushing the debris in the expansion joint. The device takes the side where the movable crushing frame 101 is located as the front side and moves forward, so as to crush the debris first and then clean the crushed debris.

[0034] like Figure 8 and Figure 9 As shown, the crushing mechanism also includes a rotary guide tube 504, a drill bit 5051, and a connecting block 506. The rotary guide tube 504 is fixedly connected to the movable crushing frame 101, the drill bit 5051 is fixedly connected to the crushing rod 505, and the connecting block 506 is fixedly connected to the crushing rod 505. The connecting block 506 is slidably disposed inside the rotary guide tube 504. The connecting block 506 can drive the crushing rod 505 to rotate by moving along the rotary guide tube 504. The crushing rod 505 drives the drill bit 5051 to rotate, which can improve the crushing efficiency. The crushing rod 505 is rotatably connected to the connecting sleeve 507.

[0035] When the connecting sleeve 507 drives the crushing rod 505 to descend, the connecting block 506 will move along the rotating guide tube 504, and at the same time drive the crushing rod 505 to rotate and descend. The drill bit 5051 at the bottom of the crushing rod 505 will also rotate and descend. The rotation makes it easier for the crushing rod 505 and the drill bit 5051 to crush the debris, thereby improving the crushing effect.

[0036] like Figure 9 and Figure 10 As shown, the connecting sleeve 507 includes a limiting plate 508, a rotating plate 509, and a third torsion spring 510. The limiting plate 508 is fixedly connected to the outside of the connecting sleeve 507, and the rotating plate 509 is rotatably connected to the outside of the connecting sleeve 507. The width of the rotating plate 509 is equivalent to the width of the expansion joint. When the rotating plate 509 rises, it scrapes away the debris remaining on the inner wall of the expansion joint. A third torsion spring 510 is provided between the rotating plate 509 and the connecting sleeve 507. The two ends of the third torsion spring 510 are respectively fixed on the rotating plate 509 and the connecting sleeve 507.

[0037] Two limiting plates 508 are provided at each rotating plate 509 on the connecting sleeve 507. When the connecting sleeve 507 descends, the rotating plate 509 is tilted upward to prevent the connecting sleeve 507 from being blocked by debris and hindering the crushing process. When the connecting sleeve 507 rises, the rotating plate 509 will swing downward and be in a horizontal state under the restriction of the limiting plate 508. At the same time, the third torsion spring 510 stores force. The horizontal rotating plate 509 will turn over the debris in the expansion joint to facilitate subsequent cleaning.

[0038] like Figure 6 As shown, it also includes a guide frame 3001, a rotating plate 4, a rotating rod 401, a spring telescopic rod 402, a second torsion spring 403, and a sliding plate 404. The rotating rod 401 is rotatably connected inside the movable cleaning frame 1. The guide frame 3001 is fixedly connected to the collection frame 3. The rotation center of the collection frame 3 is coaxial with the center of the rotating rod 401. One end of the rotating rod 401 is fixedly connected to the rotating plate 4. The worker drives the rotating rod 401 to rotate via the rotating plate 4. The end of the rotating rod 401 near the collection frame 3 is fixedly connected to the spring telescopic rod 402. A sliding connection is made inside the guide frame 3001. A sliding plate 404 is connected and slides along the guide frame 3001. One end of the spring telescopic rod 402 is rotatably connected to the sliding plate 404. A second torsion spring 403 is provided between the spring telescopic rod 402 and the movable cleaning frame 1. The torsional force of the second torsion spring 403 is greater than the spring force of the spring telescopic rod 402. The rotating rod 401 drives the guide frame 3001 and the collection frame 3 to rotate through the spring telescopic rod 402 and the sliding plate 404. The two ends of the second torsion spring 403 are respectively fixed to the spring telescopic rod 402 and the movable cleaning frame 1.

[0039] The normal state of collection box 3 is Figure 1 and Figure 2When the horizontal setting is completed and there is a lot of debris in the expansion joint or collection frame 3, first stop the movement of this device and stop the cleaning motor 2. Then, the operator manually twists the rotating plate 4. The rotating plate 4 will drive the spring telescopic rod 402 to rotate through the rotating rod 401. The second torsion spring 403 will be charged. Since the collection frame 3 is rotatably set on the moving cleaning frame 1, the spring telescopic rod 402 drives the guide frame 3001 and the collection frame 3 to rotate downward by 30 degrees through the sliding plate 404. Figure 2 and Figure 6 From the perspective of the image, the collection box 3 rotates clockwise, but is then blocked by the inclined surface of the limiting bar 104. Therefore, the collection box 3 cannot continue to rotate after rotating 30 degrees. Figure 1 From the perspective of the image, collection box 3 rotates counterclockwise, and from... Figure 1 It can be seen that the front of the collection frame 3 is blocked by the plate-like structures extending from the left and right sides of the movable cleaning frame 1, preventing debris from falling directly from the collection frame 3. Rotating the collection frame 3 by 30 degrees is to prevent it from being blocked by the movable cleaning frame 1, thereby allowing the debris in the collection frame 3 to slide out. When the rotating plate 4 is twisted further, the spring telescopic rod 402 drives the sliding plate 404 to slide along the guide frame 3001, and the second torsion spring 403 continues to store force. During the process of the sliding plate 404 sliding along the guide frame 3001 from one end to the other, the spring in the spring telescopic rod 402 first contracts and then recovers. Originally, as the sliding plate 404 slides along the guide frame 3001, it cleans the debris remaining on the bottom surface of the collection frame 3. After the rotating plate 4 is released, under the torque of the second torsion spring 403, the spring telescopic rod 402 drives the collection frame 3 to rotate 30 degrees in the opposite direction through the sliding plate 404. Then the collection frame 3 is blocked by the moving cleaning frame 1. The second torsion spring 403 continues to return to its original state and drives the sliding plate 404 to move and reset along the guide frame 3001 through the spring telescopic rod 402, thus realizing the function of cleaning the debris in the collection frame 3. Then, the staff collects and cleans the debris.

[0040] like Figure 4 and Figure 6 As shown, both the sweeping plate 306 and the sliding plate 404 are equipped with soft bristles, and the bristles on the sweeping plate 306 and the sliding plate 404 are replaceable. When the sweeping plate 306 collects debris from the cleaning plate 203 and the sliding plate 404 cleans debris remaining on the bottom surface of the collection frame 3, the soft bristles are in complete contact with the surfaces of the cleaning plate 203 and the collection frame 3, effectively removing the debris from the cleaning plate 203 and the collection frame 3. When the bristles on the sweeping plate 306 and the sliding plate 404 are damaged, they can be replaced in time to ensure cleaning effectiveness.

[0041] like Figure 9As shown, the drill bit 5051 has external threads on its outer side, which makes it easier for the drill bit 5051 to break up debris in the expansion joint; when the drill bit 5051 rotates, the external threads on the drill bit 5051 will rotate accordingly, which makes the drill bit 5051 better break up debris and improve the breaking efficiency.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
